Can anyone explain to me the difference between these two parameters used for dwa_local_planner:

**/max_trans_vel:** The absolute value of the maximum translational velocity for the robot in m/s

**/max_vel_x:** The maximum x velocity for the robot in m/s.

I mean what’s the difference between the two, I think max_tran_vel should mean compute the net velocity of the robot (I mean `sqrt(Vx^2+Vy^2)`

) and the max_vel_x is the direction of velocity along the x-direction, but, why we need to mention them separately and is there a relation between these values ? or are these params independent of each other? because this doesn’t look like that.
